Tags arbeite ich als #Bibliothekswesen an der #UniBielefeld, wo ich z.B. an der wissenschaftlichen Suchmaschine @base mitarbeite & das #GitLab der Uni betreibe.

Nachts betreibe ich ehrenamtlich Server für Datenpunks e.V. & FSuB e.V.

Neulich habe ich aus Versehen mastodon.social blockiert. Hab's rückgängig gemacht.
